Capacita' e formazione nel liberalismo di Amartya Sen e Martha Nussbaum. Eredita' differenti del pensiero politico per una "cittadinanza del mondo"

Il presente lavoro di ricerca si propone di discutere il contributo che l’analisi dell’evoluzione storica del pensiero politico occidentale e non occidentale riveste nel percorso intellettuale compiuto dai fondatori della teoria contemporanea dell’approccio delle capacità, fondata e sistematizzata nei suoi contorni speculativi a partire dagli anni Ottanta dal lavoro congiunto dell’economista indiano Amartya Sen e della filosofa dell’Università di Chicago Martha Nussbaum. Ci si ripropone di dare conto del radicamento filosofico-politico del lavoro intellettuale di Amartya Sen, le cui concezioni economico-politiche non hanno mai rinunciato ad una profonda sensibilità di carattere etico, così come dei principali filoni intorno ai quali si è imbastita la versione nussbaumiana dell’approccio delle capacità a partire dalla sua ascendenza filosofica classica in cui assume una particolare primazia il sistema etico-politico di Aristotele. Il pensiero politico moderno, osservato sotto il prisma della riflessione sulla filosofia della formazione che per Sen e Nussbaum rappresenta la “chiave di volta” per la fioritura delle altre capacità individuali, si organizzerà intorno a tre principali indirizzi teorici: l’emergenza dei diritti positivi e sociali, il dibattito sulla natura della consociazione nell’ambito della dottrina contrattualista e la stessa discussione sui caratteri delle politiche formative. La sensibilità che Sen e Nussbaum mostrano nei confronti dell’evoluzione del pensiero razionalista nel subcontinente che passa attraverso teorici antichi (Kautylia e Ashoka) e moderni (Gandhi e Tagore) segna il tentativo operato dai teorici dell’approccio delle capacità di contrastare concezioni politiche contemporanee fondate sul culturalismo e l’essenzialismo nell’interpretare lo sviluppo delle tradizioni culturali umane (tra esse il multiculturalismo, il comunitarismo, il neorealismo politico e la teoria dei c.d. “valori asiatici”) attraverso la presa di coscienza di un corredo valoriale incentrato intorno al ragionamento rintracciabile (ancorché in maniera sporadica e “parallela”) altresì nelle tradizioni culturali e politiche non occidentali.

From core rigidities to dynamic capabilities: the role of external knowledge. A multiple case study

This study focuses on the processes of change that firms undertake to overcome conditions of organizational rigidity and develop new dynamic capabilities, thanks to the contribution of external knowledge. When external contingencies highlight firms’ core rigidities, external actors can intervene in change projects, providing new competences to firms’ managers. Knowledge transfer and organizational learning processes can lead to the development of new dynamic capabilities. Existing literature does not completely explain how these processes develop and how external knowledge providers, as management consultants, influence them. Dynamic capabilities literature has become very rich in the last years; however, the models that explain how dynamic capabilities evolve are not particularly investigated. Adopting a qualitative approach, this research proposes four relevant case studies in which external actors introduce new knowledge within organizations, activating processes of change. Each case study consists of a management consulting project. Data are collected through in-depth interviews with consultants and managers. A large amount of documents supports evidences from interviews. A narrative approach is adopted to account for change processes and a synthetic approach is proposed to compare case studies along relevant dimensions. This study presents a model of capabilities evolution, supported by empirical evidence, to explain how external knowledge intervenes in capabilities evolution processes: first, external actors solve gaps between environmental demands and firms’ capabilities, changing organizational structures and routines; second, a knowledge transfer between consultants and managers leads to the creation of new ordinary capabilities; third, managers can develop new dynamic capabilities through a deliberate learning process that internalizes new tacit knowledge from consultants. After the end of the consulting project, two elements can influence the deliberate learning process: new external contingencies and changes in the perceptions about external actors.

Radar based improvements and diagnosis of the convective capabilities of the cosmo-2 model

In the last few years the resolution of numerical weather prediction (nwp) became higher and higher with the progresses of technology and knowledge. As a consequence, a great number of initial data became fundamental for a correct initialization of the models. The potential of radar observations has long been recognized for improving the initial conditions of high-resolution nwp models, while operational application becomes more frequent. The fact that many nwp centres have recently taken into operations convection-permitting forecast models, many of which assimilate radar data, emphasizes the need for an approach to providing quality information which is needed in order to avoid that radar errors degrade the model's initial conditions and, therefore, its forecasts. Environmental risks can can be related with various causes: meteorological, seismical, hydrological/hydraulic. Flash floods have horizontal dimension of 1-20 Km and can be inserted in mesoscale gamma subscale, this scale can be modeled only with nwp model with the highest resolution as the COSMO-2 model. One of the problems of modeling extreme convective events is related with the atmospheric initial conditions, in fact the scale dimension for the assimilation of atmospheric condition in an high resolution model is about 10 Km, a value too high for a correct representation of convection initial conditions. Assimilation of radar data with his resolution of about of Km every 5 or 10 minutes can be a solution for this problem. In this contribution a pragmatic and empirical approach to deriving a radar data quality description is proposed to be used in radar data assimilation and more specifically for the latent heat nudging (lhn) scheme. Later the the nvective capabilities of the cosmo-2 model are investigated through some case studies. Finally, this work shows some preliminary experiments of coupling of a high resolution meteorological model with an Hydrological one.
